Switches

550, 630 are contact switches.

An example of a toy telephone that may be used with the kitchen is shown in FIGS. 35 and 36. The telephone may include separate front and rear housings that are connected together as appreciated by the skilled artisan. The telephone 600 includes a simulated ear portion 612 and dialing portion 614 as shown.

An implementation of a telephone button embodying the principles of the invention is shown in FIGS. 37-42. The telephone button 700 includes a body portion 702 and a rim 706 with extensions 708. The telephone button 700 is mounted in aperture 518 in the answering machine 500. The button 700 may be moved inward and outward relative to the answering machine 500.

When the top surface 704 of the button 700 is pressed, the legs 708 contact an arm 632 of the telephone switch 630 to close the switch. The telephone button 700 closes the telephone switch 630 when a telephone 600 is placed in the cradle 512. The generated input signal informs the main control unit that the telephone is present.

The telephone button 700 may also be used to answer a call if the telephone 600 is not present, similar to the speaker phone function of a real telephone. When the button 700. is pressed and the switch 630 is closed, the main control unit 900 will generate an audio output, such as speech. The audio output is representative of a message that has been left on the answering machine.

An implementation of an answering machine button embodying the principles of the invention is shown in FIGS. 43-46. The structure and operation of the answering machine button is similar to that of the telephone button.

The answering machine button 800 includes a top surface 802, a rim 804, and extensions 806 as shown. The button 800 defines a cavity 808 into which a lamp extends. The button 800 is made from a transparent or semi-transparent material, such as plastic. Accordingly, the user may see light emitting from the lamp when the lamp is operated by the main control unit.

The operation of the answering machine button 800 and the answering machine switch 550 is shown in FIGS. 45 and 46.

An implementation of a main controller unit embodying the principles of the invention is shown in FIG. 47.

As shown in the functional block diagram of FIG. 47, the kitchen 10 includes a user input block 980, a control block 902, and a sensory output block 910. In response to a user input received via the input block 980, the control block 902 controls the output of selected sensory output, such as audible output (including sound effects and/or speech), visible output (including light patterns), or tactile output (including vibrations), from the output block 910.

Output block

910 includes sensory output content 920, which includes audio content 922 and video content 924. Audio content 920 can include, for example, in either digital or analog form, speech (recorded or synthesized), or sounds (including recorded natural sounds and electronically synthesized sounds). Video content 924 can include, for example, control signals for activation of lamps or other light-emitting devices.

The output content 920 can be sensibly communicated to a child for hearing or viewing by sensory output generator 930, which can include an audio output generator 940 and a video output generator 950. Audio output generator 940 can include an audio signal generator 942, which converts audio output content 922 into signals suitable for driving an audio transducer 944, such as a speaker, for converting the signals into audible sound waves. Video output generator 950 can include a video signal generator 952, which converts video output content 924 into signals suitable for driving a video transducer 954, such as lights, for converting the signals into visible light waves. The selection of the output content, and the performance attributes of the output generators, should be informed by the goal of generating sensory output that is appealing to the children playing with the kitchen.

Control block

904 controls sensory output block 910, selecting the output content to be output and activating the output generator 930 to operate on the selected output content. The operation of control block 904 can be governed by control logic 906, which can be, for example, computer software code. Control logic 906 can select content to be output repetitively or non-repetitively, randomly or in fixed sequences, and/or for short or long durations. The video and audio output can be coordinated to enhance the pleasing effect.

The controller 902 includes a mode selector 990 that selects between a shut down mode and an operating mode for the kitchen. Controller 902 includes an internal timer by which it can monitor the time that has elapsed since a command signal was received. If the elapsed time exceeds a predetermined amount of time, the main unit 900 of the kitchen 10 is powered-down to conserve energy. Once powered-down, the main unit 900 will not produce sensory output until another user input is received. The timing mechanism resets itself when the control block 904 receives a user input. If the predetermined amount of time has passed without an input, the mode selector 990 instructs the control block 904 to power-down the electronics in the kitchen.

The user input block 980 may include several user inputs. In the illustrated embodiment, the user inputs include: an answering machine.input 960, a telephone button input 962, a faucet input 964, a burner knob input 966, a burner top input 968, and a cookbook input 970. Each of these inputs is received from a corresponding switch or sensor when activated by the user (such as when a particular switch is closed). In the illustrated embodiment the switches are contact switches.

When the control block 904 receives an input from the user input block 980 via the processor 908, the control block 904 determines from the mode selector 990 which mode the kitchen is in. The relevance of which mode the kitchen is in will become apparent in the discussion of the logic sequence flowcharts below.

The operation of the kitchen will now be described. As discussed above, the operation of the lamps and the speaker 516, are controlled by controller 902. Controller 902 receives input from the user input block 980 and responds by causing the speakers and/or lights to produce sensory output depending on the mode of the kitchen. If the processor 908 recognizes signals from one of the

inputs

960, 962, 964, 966, 968, 970, the controller 902 will cause sensory output to be produced.

Power for the main unit 900 is supplied by main unit power supply, which in the illustrated embodiment consists of batteries (three C-sized cells), which are housed in a battery compartment and accessed via a battery cover.

Cookbook Logic Sequence

Turning to the sequence of operation of the kitchen relative to the cookbook, the cookbook logic sequence is set forth in FIG. 48.

When the page 300 of the cookbook 120 is turned so that one of the extension 324 contacts one of the

switches

330, 332, the

particular cookbook switch

330, 332 is closed. In step 1100, the control block 904 determines whether the cookbook input 970 received a signal from either

switch

330, 332 and forwarded it to the processor 908. If the page was not turned, the system remains in its current state.

After an input has been received from the cookbook input 970, the control block 904 determines which mode the kitchen is in from the mode selector 990 (step 1102). If the kitchen is in the power-down mode, a random message in the audio output content 922 is loaded into memory in the control block 904 (step 1104) and the lamp beneath the answering machine button flashes.

The control block 904 randomly selects between two sequence branches as shown in FIG. 48. In the illustrated embodiment, the “A” branch is selected approximately 80% of the time and the “B” branch is selected approximately 20% of the time. Note that these percentages and the percentages below are only examples and are not limited to the referenced values.

In

steps

1106 and 1108, the audio transducer 944 produces an output of speech at a level that is comfortable to the children playing with the kitchen. The particular sensory output that is generated in this embodiment is the talking script of a voice simulating a chef The script contains a few instructions related to cooking (such as “We will need spaghetti, sauce and meatballs.” or “Now add the sauce.”) and is generated by randomly selecting sentences or phrases from the memory of the audio output content 922.

After the script is played, the logic sequence of branch “B” proceeds with the Telephone Play Logic Sequence as identified in FIG. 53. Upon completion of the Telephone Play Logic Sequence, the control block 904 continues the logic of the Cookbook Logic Sequence.

At this point, the control block 904 and logic 906 is at step 1112 whether or not the kitchen was in its power-down mode. In step 1112, the control block 904 determines if an object has been placed on one of the burners of the cooking range by whether the processor 908 has received an input from the burner top input 968. If there is no object on a burner, then the controller 902 awaits for the placement of a utensil on the burner and powers-down if no input is received after a predetermined amount of time. If an object is on the burner, the control block 904 proceeds with the Burner Logic Sequence as set forth on FIG. 52.

Burner Knob Logic Sequence

Turning to the sequence of operation of the kitchen relative to the burner knobs or dials, the burner knob logic sequence is set forth in FIG. 49.

When a burner knob or dial 260 is turned, the appropriate burner knob switch 282, 284 is closed. In step 1200, the control block 904 determines whether the burner knob input 966 has received a signal from either switch 282 or 284 and forwarded it to the processor 908. If none of the burner knobs was turned, the system remains in its current state.

After an input has been received from the burner knob input 964, the control block 904 determines which mode the kitchen is in from the mode selector 990 (step 1202). If the kitchen is in the power-down mode, a random message in the audio output content 922 is loaded into memory in the control block 904 (step 1204) and the lamp beneath the answering machine button is illuminated.

The control block 904 randomly selects between two sequence branches as shown in FIG. 52. In the illustrated embodiment, the “C” branch is selected approximately 40% of the time and the “D” branch is selected approximately 60% of the time.

In

steps

1206 and 1210, the video transducer 944 produces a sensory video output from the sensory video output content 924. The particular sensory output that is generated in this embodiment is the illumination of one or both lights under the burner arrangement. When one of the lights is illuminated, the burner appears to be on and ready to cook and the child can pretend to cook food by placing a toy utensil on the burner.

After the burner light is illuminated, the control block 904 includes a timer that indicates when a predetermined amount of time has elapsed, at which point the light begins to fade and eventually shuts off (steps 1208, 1212) unless an object is placed on one of the burner portions.

After the burner light is lit, the logic sequence of branch “D” causes the control block 904 to pause a brief period, such as three to five seconds (step 1214). In step 1216, the control block 904 proceeds with the Telephone Play Logic Sequence as identified in FIG. 53. Upon completion of the Telephone Play Logic Sequence, the control block 904 continues the logic of the Cookbook Logic Sequence. The control block 904 randomly selects between two sequence branches as shown in FIG. 49. In the illustrated embodiment, the “E” branch is selected approximately 20% of the time and the “F” branch is selected approximately 40% of the time.

In the “F” branch, the audio output generator 940 generates a spoken sentence or phrase. (step 1218). In the illustrated embodiment, the spoken phrase is an instruction to the child to check the cookbook.

Returning to the determination of which mode the kitchen is in, in step 1220, the video transducer 944 produces a sensory video output from the sensory video output content 924. The particular sensory output that is generated in this embodiment is the illumination of one or both lights under the burner arrangement. When one of the lights is illuminated, the burner appears to be on and ready to cook and the child can pretend to cook food by placing a toy utensil on the burner.

After the burner light is illuminated, the control block 904 includes a timer that indicates when a predetermined amount of time has elapsed, at which point the light begins to fade and eventually shuts off (step 1222) unless an object is placed on one of the burner portions.

Faucet Logic Sequence

Turning to the sequence of operation of the kitchen relative to the faucet handle, the faucet logic sequence is set forth in FIG. 50.

When the faucet handle 400 is turned, the appropriate faucet handle switch 440 is closed. In step 1300, the control block 904 determines whether the faucet input 964 has received a signal from switch 440 and forwarded it to the processor 908. If the faucet handle was not turned, the system remains in its current state.

After an input has been received from the faucet input 964, the control block 904 determines which mode the kitchen is in from the mode selector 990 (step 1302). If the kitchen is in the power-down mode, a random message in the audio output content 922 is loaded into memory in the control block 904 (step 1304). The control block 904 randomly selects between two sequence branches as shown in FIG. 50. In the illustrated embodiment, the “G” branch is selected approximately 40% of the time and the “H” branch is selected approximately 60% of the time.

In step 1306, the audio transducer 944 produces an audio sensory output at a level that is comfortable to the children playing with the kitchen. The particular sensory output that is generated in this embodiment is the sound of running water.

After the water sounds are generated, the logic sequence of branch “G” causes the control block 904 to stop. The logic sequence of branch “H” causes the control block 904 to pause a brief period, such as three to five seconds (step 1308). In step 1310, the control block 904 proceeds with the Telephone Play Logic Sequence as identified in FIG. 53. Upon completion of the Telephone Play Logic Sequence, the control block 904 continues the logic of the Faucet Logic Sequence. The control block 904 randomly selects between two sequence branches as shown in FIG. 50. In the illustrated embodiment, the “I” branch is selected approximately 20% of the time and the “J” branch is selected approximately 40% of the time.

In the “J” branch, the audio output generator 940 generates a spoken sentence or phrase (step 1312). In the illustrated embodiment, the spoken phrase is an instruction to the child to check the cookbook.

Returning to the determination of which mode the kitchen is in (step 1302), the audio transducer 944 produces a sensory audio output from the sensory audio output content 922 (step 1314). The particular sensory output that is generated in this embodiment is the sound of running water. The sensory output is generated for a predetermined amount of time, such as five to ten seconds.

Telephone Logic Sequence

Turning to the sequence of operation of the kitchen relative to the placement of the telephone in its cradle, the telephone logic sequence is set forth in FIG. 51. The placement of the telephone is discussed with reference to FIGS. 41 and 42.

When the telephone 600 is placed.in the cradle 512 in the answering machine 500, the front housing 610 of the telephone 600 contacts the telephone button 700 that is mounted in the answering machine. Legs 708 engage arm 632 of the contact switch 630 as the telephone 600 is pressed into the cradle 512. The arm 632 is moved to close the switch 630 as shown in FIG. 42. The switch 630 generates an input.

In step 1400, the control block 904 determines whether the telephone button input 962 has received a signal from switch 630 and whether such signal was forwarded to the processor 908. If the telephone was not inserted into the cradle, the system remains in its current state.

After an input has been received from the telephone button input 962, the control block 904 determines which mode the kitchen is in from the mode selector 990 (step 1402). If the kitchen is in the power-down mode, a random message in the audio output content 922 is loaded into memory in the control block 904 (step 1404). The control block 904 randomly selects between two sequence branches as shown in FIG. 51. In the illustrated embodiment, the “K” branch is selected approximately 40% of the time and the “L” branch is selected approximately 60% of the time.

In step 1406, the kitchen wakes up from its power-down mode. The control block 904 loads a message into memory, the video output generator 950 produces a signal, and the lamp in the answering machine is illuminated. The logic sequence of branch “K” causes the control block 904 to stop.

The logic sequence of branch “L” causes the control block 904 to pause a brief period, such as three to five seconds (step 1408). In step 1410, the control block 904 proceeds with the Telephone Play Logic Sequence as identified in FIG. 53. Upon completion of the Telephone Play Logic Sequence, the control block 904 continues the logic of the Telephone Button Logic Sequence. The control block 904 randomly selects between two sequence branches as shown in FIG. 51. In the illustrated embodiment, the “M” branch is selected approximately 20% of the time and the “N” branch is selected approximately 40% of the time.

In the “N” branch, the audio output generator 940 generates a spoken sentence or phrase (step 1412). In the illustrated embodiment, the spoken phrase is an instruction to the child to check the cookbook.

Returning to the determination of which mode the kitchen is in (step 1402), the control block 904 proceeds with the Telephone Play Logic Sequence as identified in FIG. 53. Upon completion of the Telephone Play Logic Sequence, the control block 904 stops according to the logic of the Telephone Button Logic Sequence.

Burner Top Logic Sequence

Turning to the sequence of operation of the kitchen relative to the placement of an object on the top of a burner, the burner top logic sequence is set forth in FIG. 52. The placement of an object is discussed with reference to FIGS. 10A and 10B.

When an object, such as a utensil 80, is placed on the top of a burner 210, as shown in FIGS. 10A and 10B, the burner top switch 260 is closed. The arm 262 of the switch is normally in an open position. When an object is placed on the burner, the burner button 294 is pressed down to move the arm 262 to its closed position. When the switch 260 is closed, an input from the burner top input 968 is generated.

In step 1500, the control block 904 determines whether the burner top input 968 has received a signal from switch 260 and whether such signal was forwarded to the processor 908. If no object has been placed on a burner, the system remains in its current state.

After an input has been received from the burner top input 968, the control block 904 determines which mode the kitchen is in from the mode selector 990 (step 1502). If the kitchen is in the power-down mode, a random message in the audio output content 922 is loaded into memory in the control block 904 (step 1504). If the kitchen was not in its power-down mode, then step 1504 is skipped.

In step 1506, the control block 904 reviews the input signal from the cookbook input 970 to determine which side of the cookbook page 300 is not in contact with the base 226 of the cookbook 220.

If the cookbook page 300 is displaying a first side not in contact with the cookbook (step 1508), then the audio output generator 940 generates an audio sensory output signal (step 1510). In the illustrated embodiment, the first side of the cookbook page includes an illustration of spaghetti and the generated audio sensory output signal is the sound of water boiling. Note that the illustration on the cookbook page and the output signal may be changed to any particular food and/or sound.

If the cookbook page 300 is displaying a second side not in contact with the cookbook (step 1512), then the audio output generator 940 generates a different audio sensory output signal (step 1514). In the illustrated embodiment, the second side of the cookbook page includes an illustration of breakfast foods and the generated audio sensory output signal is the sound of food frying.

Each of the audio sensory output signal is generated for a predetermined amount of time, such as five to ten seconds.

If the cookbook page is positioned such that neither side of the page contacts the cookbook, then the controller 902 awaits a user input and powersdown after a predetermined amount of time (step 1516).

Telephone Play Sequence

Turning to the sequence of operation of the kitchen, the telephone play sequence is set forth in FIG. 53.

In step 1600, the audio output generator 940 generates an audio output signal. The audio output signal is the ring of a telephone and the generator 940 generates three rings. In step 1602, the control block 904 determines whether an input signal has been received from the telephone button input 962 that is indicative of whether the telephone 600 has been removed from the cradle to “answer” the call. When the telephone 600 is removed from the cradle 512, the front housing 610 is not in contact with the telephone button 700 and the switch 630 is opened. When the switch 630 is opened, there is no signal from the telephone button input 962.

If the telephone 600 was picked up by a user during the initial three rings, the audio sensory output generator 940 generates an output from a series of audio output content 922. The audio input content 922 is a spoken series of sentences or phrases. In the illustrated embodiment, the content includes script with a phrase and a closing statement, which is a statement that concludes a conversation. The script is randomly generated from a series of conversational sentences and phrases that are stored in the audio sensory output content 922. The audio output is emitted through the speaker in the answering machine. When the audio transducer 944 has played the audio output, the controller 902 stops.

If the telephone 600 was not picked up by a user during the initial three rings, the audio sensory output generator 940 generates an audio output that is played by the audio transducer 944 (step 1604). This audio output is typically one or more sentences that is a simulated message on an answering machine.

Similar to step 1602, the control block 904 determines whether an input signal has been received from the telephone button input 962 that is indicative of whether the telephone 600 has been removed from the cradle during the playing of the simulated message (step 1606). When the telephone 600 is removed from the cradle 512, the front housing 610 is not in contact with the telephone button 700 and the switch 630 is opened. When the switch 630 is opened, there is no signal from the telephone button input 962.

If the telephone 600 was not picked up by a user during the playing of the message, then the controller 902 stops and awaits another input from the input block 980.

If the telephone 600 was picked up by a user, then the audio sensory output generator 940 generates an audio output that is played by the audio transducer 944 (steps 1608 and 1610). This audio output is typically one or more sentences and a closing statement (such as “Cooking is fun”, “Bye, bye”, and “Remember to hang up the phone”). The controller 902 then stops and awaits another input from the input block 980.

Answering Machine Logic Sequence

Turning to the sequence of operation of the kitchen relative to the answering machine, the telephone logic sequence is set forth in FIG. 54. The operation of the answering machine button is discussed with reference to FIGS. 45 and 46.

When the user presses the answering machine button 800, the legs 806 of the button 800 contact the answering machine switch 550 as shown in FIG. 46. Legs 806 engage arm 552 of the contact switch 550 as the button 800 is pressed. The arm 552 is moved to close the switch 550 as shown in FIG. 46. The switch 550 generates an input signal.

In step 1700, the control block 904 determines whether the answering machine input 960 has received a signal from switch 550 and whether such signal was forwarded to the processor 908. If the button was not pressed, the system remains in its current state.

After an input has been received from the answering machine input 960, the control block 904 determines whether the audio output generator 940 is generating an audio signal corresponding to the ring of a telephone (step 1702). If such an audio signal is being generated, the video output generator 950 generates a video output signal. The video output signal is transmitted to the video transducer, which in this case is the lamp beneath the transparent answering machine button. The video output signal is an intermittent signal that simulates flashing at a frequency that is substantially equivalent to the frequency of the telephone rings (step 1716).

In step 1718, the audio output generator 940 generates an audio output signal. The audio signal is a spoken script of sentences or phrases. In the illustrated embodiment, the sentences or phrases are representative of a telephone conversation (such as “Do you know where the forks go?” and “Cooking is fun.”).

Next, the control block 904 determines which mode the kitchen is in from the mode selector 990 (step 1704). If the kitchen is in the power-down mode, the audio output generator 940 generates an audio signal indicative of a telephone message (step 1706) and a random message in the audio output content 922 is loaded into memory in the control block 904 (step 1707).

In step 1708, the video output generator 950 generates a video output that is emitted from a video transducer 954, such as the lamp beneath the answering machine button. The video output is at a different frequency than the video output generated for step 1716 as discussed above. The frequency may be more than or less than the frequency of the ringing above.

In step 1710, the control block 904 determines whether the answering machine input 960 has received a signal from switch 550 and whether such signal was forwarded to the processor 908. If the button was not pressed, the answering machine lamp continues to flash.

If the answering machine button was pressed, then the audio content that was loaded into memory during step 1707 is transmitted to the audio transducer 944 which plays the audio content. A different, random message in the audio output content 922 is loaded into memory in the control block 904 (step 1714). The controller 902 awaits the next user input and powers-down if a predetermined period of time passes without an input.

Turning to FIG. 55, a simplified schematic of the relative effect of an input on the mode of the kitchen is shown. Examples of some of the

user actions

1010, 1012, 1014, 1016, 1018, 1020 that are related to the inputs in the illustrated embodiment are shown. The outputs that correspond to the user actions are shown with the corresponding letter, for example, the activity (A) turn faucet handle corresponds to the output (A) sound of running water. The inputs are the actions that “wake-up” the kitchen from its power-down state 1000. The mode of the kitchen is changed to its operating mode 1002.

The

outputs

1030, 1032, 1034, 1036, 1038, and 1040 are examples of the audio and video sensory outputs that were described in reference to the logic sequences.

An alternate and preferred embodiment of the invention will now be described in reference to FIGS. 56 through 62. Only the differences between this embodiment and the embodiment previously described will be discussed.

Cookbook Logic Sequence

Turning to the sequence of operation of the kitchen relative to the cookbook, the cookbook logic sequence is set forth in FIG. 56. In this embodiment, the control block 904 does not select between two sequence branches as shown in FIG. 48. Also, the audio transducer 944 does not produce an output of speech as performed in

steps

1106, 1108, 1110 in FIG. 48.

Burner Knob Logic Sequence

Turning to the sequence of operation of the kitchen relative to the burner knobs or dials, the burner knob logic sequence is set forth in FIG. 57. In this embodiment, the control block 904 does not select between two sequence branches as shown in FIG. 49. In step 2210, the control block 904 determines whether an object has been placed on a burner portion. If no object is present, then the burner light is turned off. However, if an object is present, then the control block 904 proceeds with the Burner Logic Sequence in FIG. 60 (step 2212).

Faucet Logic Sequence

Turning to the sequence of operation of the kitchen relative to the faucet handle, the faucet logic sequence is set forth in FIG. 59. In this embodiment, the control block 904 does not select between two sequence branches as shown in FIG. 50.

Telephone Logic Sequence

Turning to the sequence of operation of the kitchen relative to the placement of or removal of the telephone from its cradle, the telephone logic sequence is set forth in FIG. 58. The placement of the telephone is discussed with reference to FIGS. 41 and 42. In this embodiment, the control block 904 does not select between two branch sequences as shown in FIG. 51.

Burner Logic Sequence

Turning to the sequence of operation of the kitchen relative to the placement of an object on the top of a burner, the burner top logic sequence is set forth in FIG. 60. The placement of an object is discussed with reference to FIGS. 10A and 10B.

After an input has been received from the burner top input 968, the control block 904 determines which mode the kitchen is in from the mode selector 990 (step 2502). If the kitchen is in the power-down mode, a random message in the audio output content 922 is loaded into memory in the control block 904 (step 2504) and audio output resembling a telephone conversation is generated (step 2506). If the kitchen was not in its power-down mode, then step 2504 is skipped.

In step 2508, the control block 904 determines whether the burner light is lit. If the light is not on, then no audio output is generated. If the burner light is on, then the control block determines which pages of the cookbook is selected (step 2510).

The other change from the embodiment in FIG. 52 is that the control block 904 determines whether the object has been removed from the burner portion (step 2522) while the audio output of

steps

2518 or 2520 is playing. If the object has been removed, then the audio output is stopped (step 2524), the burner light is lit (step 2526) and after thirty seconds, the light fades if no object is placed on the burner (step 2528).

Telephone Play Sequence

Turning to the sequence of operation of the kitchen, the telephone play sequence is set forth in FIG. 61. In this embodiment, the control block 904 determines whether the user has inserted or removed the telephone from its cradle (step 2602) or whether the user has pressed the answering machine button (step 2606) while the telephone rings were generated. If the user has performed either step, an audio output, such as speech, is generated and played (steps 2604, 2608).

When an audio output resembling an answering machine message is played (step 2612), then the control block 904 determines whether the user inserted or removed the telephone (step 2612) or pressed the answering machine button (step 2614) while the message is played. In order to answer a call (while the telephone is ringing), the user may press the answering machine button if the telephone is not present.

Answering Machine Logic Sequence

Turning to the sequence of operation of the kitchen relative to the answering machine, the telephone logic sequence is set forth in FIG. 62. The operation of the answering machine button is discussed with reference to FIGS. 45 and 46. In this embodiment, the only difference is the step 2700 which confirms whether a message is loaded in the machine.

As the artisan will appreciate, there are many possible variations on the embodiment of the toy kitchen 10 described above that would be consistent with the principles of the invention. Some of the variations are identified below.
